To all whom t may concern.-

Beit known that I, CARL WILLIAM OTTO ERICHSON, a subject of the King of Denmark, residing at Hamburg, in the German Empire, have invented certain new and useful Improvements in Barrel-Making Machines, of which the following is a specification.

My invention relates to the manufacture of barrels or casks and the machinery or apparatus therefor; and the objects of my said invention are an improved means for feeding particularly continuous boards provided with lateral interstices into the apparatus and for automatically rolling up said board or boards, so that the two ends meet one another, drawing the cask in at the chines, and placing auxiliary truss-hoops on the barrel, which then is released to drop out of the machine. I obtain these improvements by means of the mechanisms illustrated in the accompanying drawings, in which- Figure l is a vertical section of the entire machine on the line II Il in Fig. 2, which is a top view of the entire machine, part of the feeding-table being broken off to better show the device which serves for feeding the board. Fig. 3 shows a front view of the machine partly in section. Figs. 4 to 6 are a cross-section and two detailed views representing different positions of the slightly-modified feeding device. Figs. 7 and 8 are two detailed views of the mechanism employed to draw in the cask at the chines and to release the iinished barrel from the machine.

Similar letters refer to similar parts throughout the several views.

rlhe essential parts of the machine which I employ to carry my invention into effect are the board or stave supporting or retaining disks h b', supported by the frame of the Inachine, guided between the standards 7o 7o', and actuated by special mechanism to slide in the frame in the direction of the axis of the barrel to be formed. The said disks b b are provided with a notch ax for passing the staves or continuous board g from a table g into the circular cavity of the disks, wherein the ends of the staves or the scalloped lateral edges of the board g, forming the eask, are received and guided, while they are carried around by means of a toothed intermittently-rotated yielding ring O. The said supporting or retaining disks b b also serve to receive and carry one or more auxiliary truss-hoops P, which are to be placed on the cask or barrel after it is drawn in at the chines. This will be effected by moving the said disks h b toward one another, whereby the ends of the staves or the lateral edges of the board will enter into the truss-hoops P, whereby they are pressed firmly on the barrel to bring the staves or the scalloped parts of the board into close contact with one another.

The yielding ring O, which consists of two or more segments 0', Fig. l, toothed in their outer periphery, is slipped over a periodicallyrotated disk Y, upon which it is prevented from turning by means of a tooth or feather o, fitting to corresponding notches of either one or more of the said segments 0'. These segments o are connected with one another by bolts sliding within suitable notches in order to allow a contraction of the ring O when its supporting-disk Y is withdrawn, so that the finished barrel with the yielding ring O may be removed from the machine.

Instead of placing a yielding or contractible ring O over the intermittently-rotated disk Y and releasing the same on withdrawal of the disk, together with the barrel, toothed sectors 0X, radiating from the cent-er of rotation, are connected to the said disk Y. These sectors are guided by projections o5 of the disk Y extending through radial notches 04 of the sectors 0X, mounted under corresponding angles, to another upona rod o7, which extends through the hollow shaft Y2 of the disk Y, and may be operated by the hand-wheel o" at the end of the shaft Y2 opposite to the disk Y. The eccentries or cams oG engage either one with one of the sectors o by the aid of a notch 0S, so that on turning the rod o7 by the hand-wheel 0 the sectors will bev radially moved Von the disk Y, as may be under- IOO one of two wheels C C', movable upon a shaft C2 in front of the machine, so that a so-called chan ge-gear is formed by these three wheels` By means of a treadle E, pivoted to the frame of the machine, the said two wheels C and C' are caused to slide upon their shaft in suoli a manner that either one will mesh with the bevel-wheel B upon the aforesaid drivingshaft A', in order to transmit motion from the same through a chain-gearing D D' upon the shaft Y2 of the said feeding-disk Y and the contractible ring O. Upon the said drivingshaft A' is mounted a second wheel F, Fig. 2, operating another wheel G, which freely turns on another shaft G', located parallel to the former shaft A', and it is adapted to be periodically coupled with a disk I, iirmly mounted upon the same shaft G', and thereby to transmit motion to this shaft and to cams K K' and cranks L, fixed thereon. The cams or eccentrics are directly connected by the aid of their respective rods with the said stave supporting or retaining disk and trusshoop carrier Z9' located next thereto, while the cranks L at the ends of the said shaft G' transmit motion by means of suitable connecting-rods L' upon the other stave-supporting disk h' in such a manner that both the stave-supporting disks are simultaneously moved in their guides, either approaching to or departing from one another.

v In order to periodically actuate the shaft i G', carrying the actuating-cams K K' and cranks L by coupling the said loosely-turningwheel G with the firmly-mounted disk I, a bolt M M', guided in the latter, tends to enter, under the action of a spring N, into claws Q, projecting from the hub of the said loose wheel G, unless it is prevented from so doing by the wedge-shaped noses S or S' engaging behind a projection M of the said bolt, and thereby retaining the latter M M' from the claws of the loose wheel against the tendency of the spring N. The wedge-shaped noses S S' are secured to an oscillating arm R, pivoted to the frame of the machine and actuated by'a treadle H under the intermediation of the shaft H', lever H2, and connecting-rod H3. It', when .in the position in which the stavesupporting disks Z2' b', hereinafter also called truss-hoop carriers, are farthest from one another, the said bolt M M' is withdrawn from the claws of the said loose wheel G by means of the incline of one of the said wedge-shaped noses S, so that its shaft G' is at rest and the treadle His pressed down for a short time, and thereby the said arm R, carrying the said noses, is elevated, the said bolt M M' is then released from the respective nose S and will be instantaneously pulled against the hub of the said loose wheel G, under the action of the' spring N, and engage with the claws Q of .E the wheel. The latter is now arranged to turn the said disk I and the shaft G', whereon it is firmly secured, until the said bolt M M' is againwithdrawn from the claws of the loose wheelG byv one of the said noses S S', whereupon the shaft willbe instantaneously brought to a standstill. During this short period of the motion of the said secondary shaft both truss-hoop carriers b' b are moved from their extreme position toward one another, under the co-operation of the said eccentrics K K' and crank-disks L on the shaft G', in such a manner that the inner border of the trusshoop carriers b' h' will grasp over the ends 0f the staves or the scalloped sides of the board If the said treadle E is then released, the disk Y, with the contractible ring O, is caused to stand still, whereupon the other .treadle H is again operated, so that the said coupling-bolt M M' will be released from the corresponding nose S' of the said arm R and engage with the claws Q of the said loose wheel G on the said secondary shaft G'. In consequence thereof the shaft G', together with the said cams K K' and crank disks L, is again caused to rotate, and thereby advance the truss-hoop carriers h' b a certain distance, while the scalloped sides of the board or the staves are bulged and drawn in at the ends of the cask and the truss-hoops P placed firmly on the'same. The truss-hoop carriers b' Z2' are then withdrawn by operating again the respective treadle H, that they may return to their initial position, Fig. 7, in order to release the finished barrel, together with the truss-hoops P, while the said coupling-bolt M M', by means of the respective nose S of the arm R, is withdrawn from the claws Q of the said loose wheel and the said secondary shaft comes to a standstill.

T is a horizontally disposed rod loosely mounted in a bearing t and rigidly connected at one end to the adjacent hoop-carrier disk b'. This rod is provided with a collar T', rigidly secured thereon V is a lever fulcrumed at i) upon a stationary arm 1;', and with its lower end collarfT' of rod T is designed to engage.

W is a lever fulcrumed at its lower end and secured near its upper end to shaft Y2. This lever is on a line with lever V, so as to be moved rearward when said latter lever is turned on its pivot by the moving forward of ward each other. The upper end of lever WV is handled, so as to be manipulated. by hand.

'In consequence of the oscillation of the lever V the shaft Y2, together with the disk Y, is

`rod T, when hoop-carriers Zi' are drawn to- Withdrawn into the position indicated by dotted lines, and thereby the yielding ring O,

which is loose on said disk, is released from 'the latter, so that it .is enabled to contract or4 4er/,504 L 3 to be folded together, and to be removed, together with the nished barrel, from the machine as soon as the operator has entirely withdrawn the disk Y into the cavity of the respective truss-hoop carrier b.

Before starting the machine again for forming a new barrel new truss-hoops must of course be pnt into their rest within the trusshoop carriers b b.

Having now particularly described the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is- I.
